Archer Aviation (ACHR) Warrants to Expire September 16 as NYSE Halts Trading Under ACHR WS Symbol

Archer Aviation Inc. (NYSE: ACHR) issued a formal reminder Thursday that its publicly traded warrants will expire on September 16, 2026, at 5:00 p.m. New York City time, with the New York Stock Exchange having already halted trading in those warrants under the symbol "ACHR WS" on September 1, 2026. Any warrants left unexercised at the expiration date will become void, leaving holders with no further rights.

Warrant Expiration Details

• Exercise price: Each warrant entitles the holder to purchase one share of Archer's Class A common stock at $11.50 per share.
• Trading halt: The NYSE suspended trading of "ACHR WS" on September 1, 2026, under Section 802.01D of the NYSE Listed Company Manual.
• Suspension timeline: Trading will remain halted through September 14, with a full trading suspension taking effect before market open on September 15, 2026.
• Expiration: Warrants not exercised by September 16, 2026, at 5:00 p.m. ET expire and become permanently void.
• Common stock unaffected: Archer's Class A common stock continues to trade on the NYSE under the ticker ACHR.

Why It Matters

The warrants were originally issued under a Warrant Agreement dated October 27, 2020, between Atlas Crest Investment Corp. (Archer's SPAC predecessor) and Continental Stock Transfer & Trust Company, serving as warrant agent. Their scheduled expiration is a contractual milestone disclosed previously in Archer's second-quarter 10-Q filing, not a new or unexpected development.

With Archer's Class A common stock closing at $5.71 on Friday, September 4, 2026, the $11.50 exercise price sits well above the current market price, meaning the warrants are deeply out of the money. Exercising them at that strike would cost holders significantly more than purchasing shares directly in the open market, making unexercised expiration the likely outcome for most warrant holders. Shares fell -0.87% on Friday while the S&P 500 declined -0.39%.

Separately, according to reports published this week, Archer launched a nationwide "No Roads" flight tour under the White House Air Taxi Pilot Program and announced plans for a Los Angeles downtown vertiport developed in partnership with Anschutz Entertainment Group, underscoring the company's push to build a commercial air taxi network.

Wall Street View

Analyst sentiment on Archer remains broadly constructive, with the most recent consensus reflecting a majority Buy-leaning distribution as of September 1, 2026. No specific price target changes were disclosed in available source data for this reporting period.

Investor Takeaway

For warrant holders, the September 16 expiration is a hard deadline with no extension mechanism, and the current stock price well below the $11.50 exercise price means most warrants are expected to expire worthless. The warrant expiration itself does not affect Archer's common stock directly, but the removal of this potential dilution overhang from warrant exercises could be a modest structural positive for existing common shareholders once the expiration passes.
